Specification of Letters Patent.

Patented May 29, 1917.

Application filed. August 1, 1916. Serial No. 112,626.

To all whom it may camera:

Be it known that I, SYLVESTER ONsLow GOULD, a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented a new and useful. hlotor, of which the following is a specification.

The device forl'ning the subject matter of this application is an internal combustion engine, and one object of the present invention is to provide novel means for controlling the passage of the explosive mixture into the cylinder, and for controlling the exit of the exhaust from the cylinder.

Another object of the invention is to provide a novel form of valve ring, combined with novel means for actuating the ring, the ring controlling the ports whereby the explosive mixture is admitted, and controlling the ports whereby the exhaust is discharged.

another object of the invention is to improve the manifolds which cooperate with the valve ring.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and ar 'angement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, an internal combustion engine whereunto the device forming the subject matter of this application has been applied, parts being broken away, and parts appearing in section;

Fig. 2 is a fragmental cross section, diagrammatic in nature, and illustrating the relative positions of the valve ring and a relatively fixed port-ring on the cylinder, when an explosion is taking place;

Fig. 3 is a bottom plan of the valve ring and. attendant parts, portions appearing in section;

Fig. 4 is a view similar to Fig. 2, but illustrating the relative positions of the portring and the valve ring, when the explosive mixture is being admitted to the cylinder;

Fig. 5 is a sectional view resembling Fig. 4-, but showing the relative positions of the port ring and the valve ring while the exhaust is taking place; and

Fig. 6 is a plan view showing a different portion of the actuating worm from that disclosed in Fig. 3.

In carrying out the present invention, there is provided an engine including one or more cylinders 1, the numeral 2 denoting a piston operatively connected with a crank shaft 3 by means of a pitman a, all as usual and well understood.

Any suitable means may be provided for actuating the valve ring hereinafter de scribed. In one useful but not mandatory form of the invention, the engine carries bearings 5 in which is journaled an auxiliary shaft 6 connected with the crank shaft 3 by means of inter-meshing beveled pinions 7. Supported for rotation in bearings 26 on the engine cylinder 1 or elsewhere is a supplemental shaft 25 which, if the axis of the cylinder 1 is vertical, is horizontally disposed. The supplemental shaft 25 is connected with the auxiliary shaft 6 by means of intermeshing beveled pinions 27. Mounted on the supplemental shaft 25 and secured thereto is a worm 80 including a spiral thread 28 and a communicating thread 29, the thread 29 lying in a plane which is at right angles to the axis of the supplemental shaft 25. As hereinbefore intimated, the structure above described will be found useful in rotating the valve ring, but the particular mechanism mentioned for rotating the valve ring may be changed, should occasion demand.

The numeral 8 denotes a relatively fixed ring provided with ports 2-1, the element 8 being designated as a port-ring. The portring 8 preferably is expansible, and is divided transversely as shown at 10. The port-ring 8 is provided with a depending flange 9 which engages inside of the cylinder 1; The construction, obviously, is such that, when the port-ring 8 is supported on i the cylinder 1 as shown in Fig. 1, a leakage between the port-ring and the cylinder will not be likely to occur.

Superposed upon the port-ring 8 is a head 11. Securing elements 12 may connect the head and the port-ring 8 with the upper end of the cylinder 1.

The numeral 14: has been used to designate an annular exhaust manifold which, in

cross section, is of U-shape, as Fig. 1 will clearly disclose, the manifold 14, therefore, being open at its bottom. The exhaust manifold 1% is secured in any desired mannor, as shown at 15, to the head 11 of the cylinder. The exhaust pipe which communicates with the manifold 1% is indicated at 16. Disposed below the exhaust manifold 14 is an annular intake manifold 17 of U shape in cross section, theintake manifold, therefore, being open at its top. lhe numeral 18 denotes a conduit whereby an explosive mixture is supplied to the intake manifold 17@ The manifolds 14: and 17 may be equipped peripherally with approaching flanges 19.

At 20 there appears a valve ring surroundmg the port ring 8 closely but rotatably between the manifolds 17 and 1 1', the periphery.

ring 20 is provided with angular exhaust ports 23, the upwardly extended portions of which communicate with the exhaust manifold 1 1, the horizontal or lateral portions of which are alined with the ports 2.4: of the ring 8, and are adapted at times to commu nicate therewith. If an operating mechanism such as the shaft 25 and the worm 30 is employed, then the valve ring 20 is equipped with peripheral teeth 21 cooperating with the worm.

hen the valve ring 20 is rotated into a position such that an explosive mixture may be sucked into the cylinder 1, then, as shown in Fig. 4, the inlet ports 22 of the valve ring communicate with the ports 2d of the ring 8. At this time, the exhaust ports 23 in the valve ring are out of communication with the ports 24,111 the ring 8. YVhen an exhaust is taking place, the exhaust ports 23 in the valve ring 20 communicate with the ports 2% of the ring 8, as shown in Fig. 5, but at this time, the intake ports 22 of the v'alve ring do not communicate with the ports 24. During the explosive and compression strokes of the piston 2, the ports 24. in the ring 8 lie between the ports 22 and 23 in the valve ring 20 and consequently there is no .communication between the interior of the cylinder 1 and the exhaust manifold 14, upon the one hand, nor is there communication between the interior of the cylinder and the intake manifold 17 upon the other hand.

From the foregoing, it will be obvious that the explosive mixture passes by way of the fold 14c and thepipe 16.

Noting Figs. 3 and 6 of the drawings, it will be understood that when a tooth 21 of the valve ring 20 traverses the spiral thread 28 of the worm 30, the valve ring 20 rotates, but during the time that the said tooth is traversing the part 29 of the worm, the valve ring 20 will remain at rest. The valve ring 20 remains at rest, as aboveindicated, for a short interval, when the ports 22 and 2 1 communicate, as shown in Fig. 4c, and when the ports 23 and 2tcon1municate as shown in Fig. 5. i

For convenience-in claiming the invention,

the port ring 8 may be considered as a part of the cylinder 1, since it is fixed with respect thereto.

Having thus described the invention, what is claimed is 1. In an internal combustion engine, a

cylinder; a ring supported on the cylinder and provided with a flange engaged within the cylinder, the ring having ports; a head carried by the ring; a manifold supported by the head; a manifold assembled with the cylinder; a valve ring surrounding the first specified ring and .journaled between the ianifolds, the valve ring being provided with ports which communicate respectively with the manifolds, and are adapted to communicate with the ports in the first specified ring when the valve ring is rotated; and means for rotating the valve ring.

2. In an internal combustion engine, a cylinder having lateral ports; manifolds car ried by the cylinder; a valve ring journaled between the manifolds and provided with ports cooperating respectively with the manifolds and adapted to cooperate with the ports in the cylinder when the valve ring is rotated, the valve ring being provided with peripheral teeth; a worm including a spiral thread, and a communicating thread disposed at right angles to the axis of the worm, the teeth of the valve ring coacting with the threads; means for supporting the worm for rotation; and means for rotating the worm.

In testimony that I, claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
